Given the lack of specific data or a method (such as a regression model, moving average, or exponential smoothing) from the question, the correct answer cannot be determined directly. However, based on typical forecasting methods, if we were to assume a linear trend or a model that fits the data provided in a hypothetical Exhibit 11.5, the answer would require calculating or predicting the sales for time period 13 using that model. Since the actual calculation method or the data points are not provided, the selection of option C is based on a hypothetical scenario where the model predicts sales within the range of 2090 to 2091 for period 13.
